Abstract

Binders for coating agents, which are polycondensation products from equimolar amounts of aromatic dicarboxylic acids and diols which contain from 5 to 50% molar of the total diol amount of a neopentylglycol ester of hydroxypivalic acid and which have a melting point range of from 60.degree. to 150.degree. and a K value of from 20 to 45. The products are particularly suitable for coating strip metal.
